IMalloc::GetSize method (objidlbase.h)
Retrieves the size of a previously allocated block of memory.
SIZE_T GetSize( [in] void *pv );
A pointer to the block of memory.
The size of the allocated memory block in bytes or, if pv is a NULL pointer, -1.
To get the size in bytes of a memory block, the block must have been previously allocated with IMalloc::Alloc or IMalloc::Realloc. The size returned is the actual size of the allocation, which may be greater than the size requested when the allocation was made.
